Emma Roberts, the niece of Julia Roberts, could be a candidate for invisible braces in future.

In an interview with Women's Health magazine, she drew attention to her "really crooked teeth", which she said she doesn't mind too much at the moment because they "give me character".

However, the Scream 4 performer added: "We Robertses have too many teeth for our mouths."

This could cause problems in the future when her wisdom teeth erupt, as it may act to push the other teeth further out of alignment.

Should this happen, Roberts' dentist may suggest invisible braces to realign them again.

Justin Bieber recently admitted in an interview with Rolling Stone magazine that he has been wearing invisible braces.

He explained that he had to have some teeth removed that were pointing inwards, but this created a gap that is now being closed with the aligners. He wears them every day apart from when he is eating and brushing.

People with Invisalign products do not have to worry about any food getting stuck in their braces.

This is according to World Dental, which claimed invisible braces of this kind have several advantages over traditional dental aligners.

As well as the obvious cosmetic benefits of the device, Invisalign can offer patients improved oral hygiene because the braces are removable.

This means they can be taken out before eating, thereby reducing the risk of food items becoming stuck and causing infections in the mouth.

The website pointed out that Invisalign braces are "not for everyone" and will be unsuitable for young children in the majority of cases, as the jaw and teeth must already be well developed for the device to be effective.

"However, they offer a great option for many adults and teens," it added.

Earlier this month, teen pop idol Justin Bieber revealed in an interview with Rolling Stone magazine that he has been using invisible braces to straighten his teeth.
